Permissions issue

[yiuqinze]

I have a question now
For example, I have two directories /home/test1 /home/test2. I have a local storage used by haha user. I specified that his home directory is /home/test1. I also want this user to access /home/test2. I added times. Group, but when users access it, they can only see the content in the main group directory and cannot see the content in the sub-group.
